One of the cool new features in version 1.2 is that EPF Composer supports
shell sharing with Eclipse 3.3. So, if you already have Eclipse 3.3 on your
machine you can install EPF Composer just right into it. Just copy-paste
everything from EPFC's features and plugins directories into the respective
directories of Eclipse 3.3 and start it. (It will prompt you to override
files, but if you use the Eclipse and EPF release versions it will just
override the same files. If you do this with updated versions of Eclipse,
check which files you are overriding one by one).

You can now take advantage of useful Eclipse plugins for EPF Composer. For
example, you can use Mylyn to directly and graphically search, modify, and
create bugzillas on bugs.eclipse.org . See this screen shot for an example: http://haumer.net/images/epfc-with-mylyn.gif

All you need to do is to open the Mylyn views inside your authoring view.
The "Task Repositories" view already has bugs.eclipse.org pre-configured.
All you have to add is you username and password (double-click). The Task
List shows bugs that yo manually added here. Click on the little arrow
symbol on the right and "Search Repository.." to run a query. You add the
bugs to your list via a right-click on the search results. Very handy
extension.
